摘要：

In this paper, entropy weight method is used to sort the indicators, which can avoid human subjectivity. As a typical coastal city, Dalian is selected as a case study to verify the applicability of the method. A water resource sustainable utilization index system including 15 indicators is built which involves water resource, society, economy and environment. The improved catastrophe progression method is provided and used to evaluate sustainable utilization of water resources situation in Dalian from 2002 to 2012. Results indicate that except 2002, the sustainable utilization index of water resources is around 0.8 from 2003 to 2012, which shows a strong degree of sustainability. The results are found to be coincident with practical situation, so it proves that the improved catastrophe progression method has good applicability.
